Too many lie-ins worse than too little sleep

Researchers from the University of East Anglia, Leeds University, and Manchester concluded that people who sleep over eight hours a night saw an increase in heart disease by 44%.

They analyzed the data from 74 studies which contained information on the sleep quality and habits of three million people (from 1970 to 2017).

However, it was generally thought that too little sleep was far worse than too much.

Current recommendations suggest that adults should sleep for eight hours a night and although the precise benefits of sleep are still unknown, experts believe it gives the body a chance to fix cells and blood vessels, clear out waste and boost the immune system.

A major study has found getting more than 10 hours of sleep a night increased the chances of death from stroke by 56% and heart disease by 49%.

"Our study has an important public health impact in that it shows that excessive sleep is a marker of elevated cardiovascular risk".

"Our findings have important implications as clinicians should have greater consideration for exploring sleep duration and quality during consultations".

Researchers at Keele University found out that people who like to sleep over eight hours a night are more likely to develop different conditions which cause premature death.

The results show that sleeping for longer than the recommended duration of seven or eight hours may be associated with a moderate degree of harm, compared to those who sleep for shorter durations. The amount and quality of our sleep is complex.

Dr Kwok, a clinical lecturer in cardiology at Keele, added: "This research began because we were interested to know if it was more harmful to sleep below or beyond the recommended sleep duration of seven to eight hours".

'There are cultural, social, psychological, behavioural, pathophysiological and environmental influences on our sleep such as the need to care for children or family members, irregular working shift patterns, physical or mental illness, and the 24-hour availability of commodities in modern society'.
